soc/intel/skylake: Add GPIO macros for IOxAPIC and SCI
Add two GPIO macros:
1. PAD_CFG_GPI_APIC_EDGE allows a pin to be route to the
APIC with input assuming the events are edge triggered.
2. PAD_CFG_GPI_ACPI_SCI_LEVEL to route the general purpose
input to SCI assuming the events are level triggered.
